Determine the Vertex in Vertex Form

What does the k term tell you?

• up.

• down.

• up/down, y-value in the vertex

• nothing

• Factored Form

• Standard Form

• Vertex Form

• a=-1, h=3, k=2

• a=3, h=3, k=3

• a=1, h=-3, k=2

• a=1, h=-3, k=-2

Identify the a, h, and k terms in the following equation: 2\left(x+4\right)^2-1

• a=2, h=-4, k=-1

• a=-2, h=4, k=1

• a=2, h=4, k=1

• a=-2, h=-4, k=1

The graph of a quadratic function is shown. The vertex and two points are labeled. Drag and drop the numbers and operations to write the equation for the parabola in vertex form. y = ​ (a)   (x​​ (b)   (c)   )² - (d)

Identify the vertex and whether the graph opens up or down. (a)  

• (5, 2); opens up

• (5, 2); opens down

• (-5, 2); opens up

• (-5, 2); opens down
